This invention relates to guards for electric trouble lights, the primary object of the invention being to provide a guard for trouble lights wherein the sections of the guard may be moved with respect to each other, exposing the electric light bulb held in the socket oi the trouble light, so that the bulbmay be readily and easily re-- moved and replaced.

An important object of the invention is to provide a device of this character which will be securely connected with the socket of the trouble light at all times, so that it is unnecessary to disconnect the guard from the socket of the trouble light, in replacing a defective lamp or electric bulb.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is an elevational view illustrating a trouble light constructed in accordance with the invention, the solid section of the guard being shown as swung to an open position, in dotted lines.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Referring to the drawing in detail, the reference character 5 indicates the handle of the trouble light, which is provided with the socket 6 at its outer end.

The guard forming a part of the trouble light, includes a solid section 1 which provides a reflector for directing light rays forwardly, and a cooperating guard section made up of spaced longitudinal and transverse rods, indicated by the reference character 8. The section 1 includes a clamp 9 to which the longitudinal rods of the section 8 are secured, the ends of the clamp having openings to receive the bolts In, which bolts also pass through openings formed in the ends ll of the clamp section I2, there being provided spacer nuts l3 between the adjacent ends of the clamp sections, holding the clamp sections in proper spaced relation with respect to each other. Nuts M are also provided on the bolts and provide means for drawing the ends of the clamp sections together in securing them around the socket 6.

As clearly shown by the drawing, the solid section I of the guard is provided with ears I that are so constructed and arranged that they fall opposite to the bolts l0, when the solid section is moved to guard the light bulb in the socket. These ears are formed with openings so that the bolts may extend therethrough and hold the solid section of the guard in position. The reference character Hi indicates a coiled spring which is provided with hooks H at its ends, which hooks are hooked around certain of the rods of the section 8, the spring being stretched around the lower end of the solid section 1, holding the solid section of the guard into contact with the nuts i4, and firmly securing the solid section of the guard to the socket 6.

An car it is formed at the outer end of the solid section I, the ear having an opening so that the hook IS at the outer end of the guard, may be passed therethrough, pivotally connecting the solid section of the guard to the section 8.

From the foregoing it will be seen that when it is desired to replace the light bulb, it is only necessary to disconnect one end of the coiled spring from the guard, allowing the solid section of the guard to be swung away from the cooperating section of the guard in a manner as shown by the dotted lines in Fig. 1. It will now be seen that the lamp bulb may be readily removed and replaced and the solid section I of the guard returned to its guarding position around the light bulb, which is indicated by the reference character 20.

The coiled spring I6 is now hooked around one of the rods of the guard, which holds the solid section of the guard in position, against accidental displacement.

From the foregoing it will be seen that the time required in replacing a light bulb, is reduced to a minimum, and the replacement may be made without the use of tools of any kind.

Having thus described the invention, what is claimed is:

The combination with the light bulb and light bulb socket of a trouble light, of alight bulb guard comprising a wire section and a solid reflecting section, said wire section including a clamp to which said wires are connected, said clamp adapted to be secured around said light bulb socket of the trouble light, a supporting hook formed on said wire section, extending a substantial distance beyond the end of the wire section, an apertured ear extending from one end of the solid reflecting section through which said hook extends pivotally and slidably connecting the solid reflecting section to the wire section, a coiled spring having hooks at its ends, hooked around the Wires of the wire section and stretched around the solid reflecting section, removably securing the sections of the guard around a light bulb.

FORREST GLENN GRAVES.
